That the price to take a small carryon was just as expensive as taking a large suitcase, ended up having to pay and extra $80 r/t for a small bag and I just that's standard for them. There were no barf bags in any seats, believe me everyone around us was looking as the person next to me was getting sick on the landing because it was crazy rough. When we finally were able to get an attendant over she was as rude as could be, I'm sure this sick person next to me was sorry she "inconvenienced" the crew member, if they just put bags in the seats pockets like every other airline this wouldn't have been an issue. The seats were very uncomfortable with no padding and not able to tilt. The tray tables were nonfunctional, too small and did not extend to get anywhere close enough to reach you. The plane ride itself felt like we were on a old school bus on a gravel road. I had a round trip ticket with frontier and both trips were equally as bad. I will never travel with them again, Most of us weren't even sure if we were going to survive take off with out the plan breaking or something.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
